Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment technology for chemical production, and in particular to a filter press for the production of zirconium oxychloride. Background Technology

[0002] Zirconium oxychloride, as an important zirconium chemical, has wide applications in the fields of ceramics, nuclear industry and catalysts.

[0003] One of the key steps in its production process is the solid-liquid separation of the reaction products to obtain high-purity zirconium oxychloride solid products. As the core equipment for achieving solid-liquid separation, the performance of the filter press directly affects the quality and production efficiency of zirconium oxychloride products.

[0004] Zirconium oxychloride suspension contains a large number of fine particles and impurities. These substances can easily clog the filter cloth pores during filtration, leading to increased filtration resistance and decreased filtration efficiency. Frequent disassembly and cleaning are required, which not only increases maintenance costs, but also makes the solid waste after pressure filtration prone to sticking together, requiring manual cleaning and affecting the continuity of production. Utility Model Content

[0005] To address the technical problem of impurities clogging filter cloth in existing zirconium oxychloride suspensions, this invention provides a filter press for zirconium oxychloride production.

[0006] The technical solution of this utility model is achieved through the following scheme: a filter press for the production of zirconium oxychloride, including a filter press, a cleaning device, a material receiving device and a controller, wherein the material receiving device is provided below the filter press, and the cleaning device is slidably installed on the filter press through a first screw moving device;

[0007] The cleaning device includes a cleaning support frame, a unloading assembly, and a pneumatic cleaning assembly. The cleaning support frame is connected to a bearing plate via a second lead screw moving device. The unloading assembly and the pneumatic cleaning assembly are mounted on the bearing plate. The cleaning support frame is slidably mounted on a first lead screw moving device. A lever is mounted on one end of the cleaning support frame near the first lead screw moving device. The filter press, the cleaning device, the first lead screw moving device, the second lead screw moving device, and the receiving device are all communicatively connected to a controller.

[0008] Through the above technical solutions, the first screw moving device drives the cleaning device to move laterally along the filter plate arrangement direction of the filter press, achieving full filter plate coverage cleaning. The second screw moving device controls the cleaning support frame to reciprocate in the direction perpendicular to the filter cloth, working in conjunction with the pneumatic cleaning component and the unloading component to achieve three-dimensional cleaning, completing the dual screw collaborative operation and reducing manual intervention. The unloading component directly acts on the solid material produced after filtration by the filter press, quickly and effectively peeling the solid material from the filter cloth and pushing it into the receiving device. Compared with the traditional manual unloading method, it greatly improves the unloading efficiency, reduces the unloading time, and makes the production process more compact. The pneumatic cleaning component uses high-speed airflow to effectively blow away the residual powder particles in the filter cloth, achieving deep cleaning, reducing frequent disassembly, and the non-contact working method of airflow blowing avoids the wear or damage to the filter cloth that may be caused by direct contact between the cleaning tool and the filter cloth.

[0009] Preferably, the unloading assembly includes a first scraper, a second scraper, and a plurality of drive cylinders. The end of the first scraper away from the filter press is rotatably mounted on the support plate, and the other end of the first scraper is hinged to a plurality of drive cylinders. The end of the second scraper away from the filter press is fixedly mounted on the support plate, and the other end of the second scraper is fixedly mounted on the support plate by a plurality of fixing rods.

[0010] Preferably, the drive cylinder is located inside the support plate.

[0011] Through the above technical solution, the first scraper and the second scraper work together to quickly and efficiently remove the solid material produced after filtration from the filter cloth, improving the unloading efficiency. The first scraper can be adjusted according to the position of the filter plate being pried open by the prying plate component. The angle of the first scraper is adjusted by the drive cylinder to better fit the pryed-open filter plate, thereby improving the scraping effect, improving the adaptability and reliability of the unloading component, and ensuring that the material is completely scraped off the filter plate. Meanwhile, the filter plate on the other side is still in a state of multiple compressions, so the angle of the second scraper does not need to be adjusted.

[0012] Preferably, both the cleaning support frame and the bearing plate have air ducts.

[0013] Preferably, the starting cleaning assembly includes a fan, a telescopic duct, an air outlet, and an air outlet block. The fan is mounted on the cleaning support frame. The fan is connected to the telescopic duct through the air duct of the cleaning support frame. The telescopic duct is connected to the air outlet and the air outlet block through the air duct of the support plate. The support plate has several air outlets. The air outlet blocks are located on both sides of the support plate near the second lead screw moving device.

[0014] Through the above technical solutions, air ducts are created within the internal space of the cleaning support frame and the carrier plate, allowing for smoother and more efficient airflow. This reduces airflow resistance losses during transmission, ensuring that the pneumatic cleaning components have sufficient air volume and velocity to remove powder particles from the filter cloth, thus improving the cleaning effect. The telescopic air duct can adapt to changes in the position of the cleaning support frame under different working conditions, ensuring the versatility and adaptability of the pneumatic cleaning components. Multiple air outlets can simultaneously discharge air, cleaning the filter cloth from different directions, making it easier for powder particles to be blown away by the airflow. The air outlet blocks are located on both sides of the carrier plate, allowing for focused cleaning within the angle between the scraper and the carrier plate, avoiding powder residue and improving overall cleanliness.

[0015] Preferably, the receiving device includes a waste box, a discharge box, and a waste conveying roller. The waste box has discharge boxes on both sides arranged opposite to each other, and the waste conveying roller is installed inside the waste box.

[0016] Through the above technical solutions, by driving the waste conveying roller to rotate, the waste can move in a certain direction under the action of the conveying roller, realizing the automatic conveying of waste, avoiding excessive accumulation of waste in the waste box, which would affect subsequent unloading and collection work, and ensuring the continuity and stability of the entire production process.

[0017] In summary, this utility model has the following beneficial effects:

[0018] 1. This utility model uses a first screw moving device to drive the cleaning device to move laterally along the filter plate arrangement direction of the filter press, achieving full filter plate coverage cleaning. The second screw moving device controls the cleaning support frame to reciprocate in the direction perpendicular to the filter cloth. Together with the pneumatic cleaning component and the unloading component, it achieves three-dimensional cleaning, completing the dual screw collaborative operation and reducing manual intervention. The unloading component directly acts on the solid material produced after filtration in the filter press, quickly and effectively peeling the solid material from the filter cloth and pushing it into the receiving device. Compared with the traditional manual unloading method, it greatly improves the unloading efficiency, reduces the unloading time, and makes the production process more compact. The pneumatic cleaning component uses high-speed airflow to effectively blow away the residual powder particles in the filter cloth, achieving deep cleaning, reducing frequent disassembly, and the non-contact working method of airflow blowing avoids the wear or damage to the filter cloth that may be caused by direct contact between the cleaning tool and the filter cloth.

[0019] 2. The first and second scraper plates work together to quickly and efficiently remove the solid material produced after filtration from the filter cloth, improving unloading efficiency. The first scraper plate can be adjusted according to the position of the filter plate being pried open by the prying plate component. The angle of the first scraper plate is adjusted by the drive cylinder to better fit the pryed-open filter plate, improving the scraping effect and enhancing the adaptability and reliability of the unloading component. This ensures that the material is completely scraped off the filter plate, while the other side of the filter plate remains in a multi-piece compression state, thus eliminating the need for angle adjustment of the second scraper plate.

[0020] 3. By utilizing the internal space of the cleaning support frame and the carrier plate to create air ducts, airflow can be made smoother and more efficient, reducing air resistance loss during transmission and ensuring that the pneumatic cleaning components have sufficient air volume and speed to blow away powder particles from the filter cloth, thus improving the cleaning effect. The telescopic air duct can adapt to changes in the position of the cleaning support frame under different working conditions, ensuring the versatility and adaptability of the pneumatic cleaning components. Multiple air outlets can simultaneously blow air from different directions, making it easier for powder particles to be blown away by the airflow. The air outlet blocks are located on both sides of the carrier plate, allowing for focused cleaning within the angle between the scraper and the carrier plate, avoiding powder residue and improving overall cleanliness.

[0021] 4. By driving the waste conveying roller to rotate, the waste can move in a certain direction under the action of the conveying roller, realizing the automatic conveying of waste, avoiding excessive accumulation of waste in the waste box, which would affect the subsequent unloading and collection work, and ensuring the continuity and stability of the entire production process.

[0034] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0035] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification. The present invention will be further described in detail below with reference to the accompanying drawings.

[0036] A filter press for zirconium oxychloride production, such as Figures 1-7 As shown, it includes a filter press 1, a cleaning device, a material receiving device 8, and a controller 9. The material receiving device 8 is located below the filter press 1. The cleaning device is slidably installed on the filter press 1 through the first screw moving device 5. The material receiving device 8 is located directly below the filter plate of the filter press 1 to collect materials and waste.

[0037] The cleaning device includes a cleaning support frame 2, a discharge assembly 3, and a pneumatic cleaning assembly 4. The cleaning support frame 2 is connected to a bearing plate 7 via a second lead screw moving device 6. The discharge assembly 3 and the pneumatic cleaning assembly 4 are mounted on the bearing plate 7. The cleaning support frame 2 is slidably mounted on a first lead screw moving device 5. A lever 10 is mounted on one end of the cleaning support frame 2 near the first lead screw moving device 5. The filter press 1, the cleaning device, the first lead screw moving device 5, the second lead screw moving device 6, and the receiving device 8 are all communicatively connected to a controller 9. The first lead screw moving device 5 is located on the side of the filter press 1. The cleaning support frame 2 is generally U-shaped, with one end connected to the first lead screw and the other end equipped with a limiting guide wheel installed in a limiting slide rail. It slides under the drive of the first lead screw motor. Lever 10 (existing technology). The cleaning support frame 2 is installed on the two legs inside the "U"-shaped cleaning support frame 2 and is set opposite to each other. After the filter press is completed, the cleaning support frame 2 slides on the first screw moving device 5 and moves to the appropriate position to open the filter press plate. The unloading component 3 and the pneumatic cleaning component 4 are raised and lowered on the second screw moving device 6 to clean solid waste and blow holes. The unloading component 3 removes solid waste from the surface of the filter cloth and the grooves of the filter press plate. The pneumatic cleaning component 4 blows out fine particles and impurities in the pores of the filter cloth, effectively reducing the filtration resistance, restoring the filtration performance of the filter cloth, and ensuring the efficient operation of the subsequent filter press process. The bearing plate 7 has a chamfer at one end near the filter press 1, forming a triangle and is longer than the unloading component 3, which can assist the plate-moving component 10 in moving the plate. The second and fourth moving devices are located inside the two legs of the "U"-shaped cleaning support frame 2.

[0038] like Figure 5 As shown, the unloading assembly 3 includes a first scraper 31, a second scraper 32, and several drive cylinders 33. The end of the first scraper 31 furthest from the filter press 1 is rotatably mounted on the support plate 7, and the other end of the first scraper 31 is hinged to several drive cylinders 33. The end of the second scraper 32 furthest from the filter press 1 is fixedly mounted on the support plate 7, and the other end of the second scraper 32 is fixedly mounted on the support plate 7 via several fixing rods. One end of the first scraper 31 is connected to the support plate 7 via a rotating shaft. The drive cylinders 33 are located within the support plate 7 and are lifted by the drive cylinders embedded within the support plate 7, allowing the first scraper 31 to change angle around the rotating shaft. Both the first scraper 31 and the second scraper 32 have chamfered ends near the filter press 1 to facilitate scraping solid waste, reduce scraping resistance, and improve scraping efficiency. The drive cylinders 33 are hinged to the first scraper 31, and their hinge holes (e.g., Figure 6 (As shown) is a strip hole used to provide space for the horizontal movement of the hinge axis.

[0039] like Figure 2As shown, when the filter press 1 releases the press pressure, the pry plate 10 will pry open one filter plate. On the other side, multiple filter plates are still pressed and fixed. Therefore, the second scraper 32 is fixedly tilted and the angle will not change. The scraping angle is adapted to the side where multiple filter plates are pressed and fixed. When the bearing plate 7 sinks with the unloading assembly 3, it can be adjusted to a suitable scraping angle by the drive cylinder 33. The solid waste fixed on the filter plate is successfully scraped by the chamfers of each end close to the filter press 1.

[0040] like Figure 4 As shown, both the cleaning support frame 2 and the support plate 7 have air ducts, which are channels. Multiple interconnected channels are opened in the cleaning support frame 2 and the support plate 7, allowing airflow to flow smoothly within the air ducts and providing a channel for subsequent airflow delivery. Both sides of the support plate 7 have several air outlets 43. The air outlets 43 are equipped with filters and are set upwards to prevent solid materials from entering and effectively prevent solid materials from entering the air outlets 43 under the action of gravity, ensuring normal airflow.

[0041] The cleaning assembly includes a blower 41, a telescopic duct 42, an air outlet 43, and an air outlet block 44. The blower 41 is mounted on the cleaning support frame 2. The blower 41 is connected to the telescopic duct 42 through the air duct of the cleaning support frame 2. The telescopic duct 42 is connected to the air outlet 43 and the air outlet block 44 through the air duct of the support plate 7. The support plate 7 has several air outlets 43. The air outlet blocks 44 are located on both sides of the support plate 7 near the second lead screw moving device 6. The air outlets of the air outlet blocks 44 face the sandwich surface between the two scraper plates and the support plate 7, and blow away the solid material stuck to the sandwich surface. The air outlets 43 are opened on the unloading assembly 3. After the scraper plates scrape away the solid material on the surface, the air outlets 43 blow away the particulate material that clogs the filter cloth, ensuring the cleanliness of the sandwich surface between the scraper plates and the support plate 7. The telescopic duct 42 can effectively extend or retract in accordance with the rise and fall of the support plate 7.

[0042] like Figure 7 As shown, the material receiving device 8 includes a waste box 81, a discharge box 82, and a waste conveying roller 83. The waste box 81 has discharge boxes 82 arranged opposite to each other on both sides. The waste box 81 is equipped with waste conveying rollers 83, which are rotating screw rollers. Preferably, there are two of them. The two rotating screw rollers cooperate with each other and convey the material along the axial direction by their own rotation, which can enhance the conveying capacity and improve the conveying efficiency, ensuring that the solid material can be stably and continuously conveyed out of the waste box 81. Two motors are connected to drive it. The waste box 81 has an inverted trapezoidal slot. The wider upper part can collect the solid material scraped by the scraper more widely and avoid the material from scattering during the collection process. The narrower lower part helps to guide the material to flow downward, which is convenient for subsequent conveying and processing. The discharge boxes 82 on both sides collect the material discharged from the filter cloth.

[0043] Working principle: When the filter press 1 releases the press pressure, the two pry plates 10 will first pry open one filter plate. At this time, the bearing plate 7, driven by the second screw moving device 6, carries the unloading assembly 3 down. During this process, the drive cylinder 33 starts to work. According to the actual scraping requirements, the first scraper 31 is adjusted to a suitable scraping angle and cooperates with the fixed and inclined second scraper 32. Using the chamfer of each end close to the filter press 1, the solid waste fixed on the filter plate is successfully scraped.

[0044] After the scraper removes the solid material from the filter press 1, the material falls into the waste box 81. Under the action of gravity and the shape of the waste box 81, the material gathers at the bottom of the waste box 81. At this time, the two external motors start and drive the two waste conveying rollers 83 to start rotating. The rotating screw rollers will transport the solid material gathered at the bottom of the waste box 81 along the axial direction, completing the material collection and conveying process.

[0045] After the scraper removes solid material, the cleaning assembly is activated, and the blower 41 starts running, generating airflow. The airflow enters the telescopic air duct 42 through the air duct in the cleaning support frame 2, and then is transported to the air outlet 43 and the air outlet block 44 through the air duct in the bearing plate 7. Part of the airflow blown out from the air outlet 44 blows directly onto the sandwich surface between the two scraper blades and the bearing plate 7, blowing away the solid material stuck to the sandwich surface. Another part of the airflow blows out from the air outlet 43 on the unloading assembly 3, cleaning the filter cloth after the surface solid material has been scraped off by the scraper blades, removing the particulate material clogging the filter cloth. Throughout the process, the filter screen in the air outlet 43 of the bearing plate 7 can effectively prevent solid material from entering the air duct, ensuring the normal flow of airflow and the normal operation of the cleaning assembly.

[0046] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
